Hello, I am working on a small library of *useful* (kinda) functions that add to c++, This is mainly for me, as i'm too lazy to write long functions to do a simple task like printing a new line.
I have these three files :
Header :
Code:
implementation :
Code:
& demo program :
Code:
when I compile with clang++ main.cpp -std=c++19 -o main.exe
i get these errors :
Code:
what am I doing wrong?
I have these three files :

};
};
